Embodiment Construction

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] See figure 1 , which is a flow chart of an embodiment of the control method based on the inverter air conditioner of the present invention.

[0032] Such as figure 1 As shown, the embodiment implements the inverter air conditioner control method, specifically, the specific process of realizing the wall-mounted inverter air conditioner refrigeration control method is as follows:

[0033] Step 101: The air conditioner is turned on, and the compressor is controlled to run.

[0034] After the air conditioner is turned on, it will control the operation of the compressor according to the user-set or default operation mode and operation parameters, and according to the predetermined control program.

[0035] Step 102: Judging whether the air conditioner enters room temperature PID control. If yes, go to ...

Abstract

The invention discloses a control method of a variable-frequency air conditioner. The control method comprises the following steps that the air conditioner is started to run a refrigeration mode, and when the air conditioner enters indoor temperature PID control, the current indoor temperature detected by an indoor temperature sensor is obtained and serves as a first indoor temperature; the difference value between the first indoor temperature and a set compensation temperature serves as a second indoor temperature, the temperature difference between the second indoor temperature and the current indoor target temperature is calculated, and the indoor temperature difference is obtained; indoor temperature PID operation is conducted according to the indoor temperature difference, so that a first target frequency is obtained; the second indoor temperature is compared with a set comfortable temperature, whether indoor temperature PID control or double PID control including coil pipe temperature PID control needs to be conducted is determined according to the comparing result; and the target coil pipe temperature adopted for coil pipe temperature PID control is determined according to the current indoor target temperature. By adopting the control method, the comfort of indoor temperature adjustment of the air conditioner and the low power consumption and energy conservation of the air conditioner are achieved simultaneously, and more reasonable control is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method of an inverter air conditioner. Background technique [0002] In the hot summer, many people cannot do without the air conditioner all day and all night. However, blowing air conditioners for a long time has many harms to the human body, and it is easy to get air conditioner diseases. [0003] In order to solve the uncomfortable problem caused by cold air blown out by refrigeration, the control method of controlling the operating frequency of the compressor can be based on the coil temperature of the indoor heat exchanger as the control target. In the existing coil temperature control process, the target temperature of the coil adopts a fixed value, which is generally a fixed temperature value solidified in the storage of the air conditioner. In actual use, there is often a phenomenon: when the indoor target temperature set by the user is d...
